I used to have a couple of acoustic foam diffusers/absorbers on the walls, but my cats tried to devour them... I am however planning on building bass traps for the corners and 2 or 3 additional units along one wall. This time around they will be pet proof.
I reckon by screen size you mean the projector screen hidden in the roof? It's a 104" screen, sparsely used lately though, my projector is starting to give up.
Regarding the ribbon tweeters. They produce a lot of details and have a "presence". I cannot really explain, I just like the sound the speakers produce.

Yeah I noticed the slot in the ceiling for the screen haha, I built my projector screen about 2 years ago and could never go back to a regular size TV now. My speakers are the Chane A5rx-c's which have a flat panel leaf tweeter that I really enjoy as well, I put my speakers up for sale as I was going to switch over to three T1 towers but no bites on the Chanes and selling three could be a hard thing to accomplish. My speakers sit behind my screen and I have a few panels behind them as well

So I have been using the T2's for little while now and I have played around a bit more with EQ. The high frequencies was a bit too sharp for my ears so I toned them down a wee bit. I currently have a 3.1 system after I sold my old set of speakers, so I thought I should try use the 2 leftover channels on my UPA-5 to bi-amp the T2's. With more power the bass really came to life. Looking to buy the E2's later, but now I also need to buy another AMP But first some work with the room must be done, it's like an echo chamber now. Will build a couple of combined bass traps and diffusers, something like this is the plan.

I will be trying the new DR-2 with my T-2's this weekend. Now, I have the T-2 powered by a Yamaha A-S2000, and an XDA-2. I Wonder how they will combine together !.

Hey this is my first post here. I bought the T2's and have been using them for more than a month now. They sound fantastic and are great. The bass is powerful and very well balance. The mids and highs are unbeatable.
But I started noticing a issue a week into usage but didn't focus on it thinking that it is just my hearing. So what was it?
I started to feel that left speaker is overpowered by right one, causing the stereo imaging not to feel centred.
So I ventured in to science to find out if indeed there was a problem or is it just a feeling in my head.
After various basic tests which involved swapping speakers, cables, amplifiers. I could always fault one particular speaker and the problem moved with it wherever I kept it. So then I resorted to measure the difference and used a white noise generator on ipad pro together with db meter reader on a mobile device to get readings.
Readings were made with complete silence
A) in their original positions. B) swapped positions. C) central position, keeping other speaker out of room. D) swapping output from amplifier ( giving each speaker left out and right out from amp)
Only one things was consistent and that was that the original LEFT SIDE speaker always sounded lower than the RIGHT SIDE speaker no matter where placed, which output was it given.
This only left one thing in mind that both the speakers are not perfectly matched despite left and right marked distinctively on the packaging cartons.
The difference according to my db meter readings at various output levels for both white noise and pink noise varied from 0.25 db to 0.60 db.
It can't be level matched in my system because my system offers balancing in 1 db increments. It causes the stereo Imaging to be Coming from one side always and is never centred.
I have already contacted the dealer who is saying issue will be bought up to the manufacturer.
Any ideas?

A 0.25 to a 0.6 dB difference between speaker pairs is within normal manufacturing tolerances. It would not be considered a defect by the vast majority of speaker manufacturers. KEF’s models built for the BBC met more stringent matching specs, as did the late Jim Thiel’s products, but they’re the exceptions, not the rules.
If you can’t compensate for the mismatch with your balance control, and the issue still bothers you (apparently the case on both fronts), then try moving the weaker speaker two or three inches at a time toward a side wall until the outputs balance. Otherwise, speak with Emotiva - they value customer satisfaction.
Best of luck!

The in room frquency response will potentially be different if you measure the speakers individually. I would venture to suggest it will always be different. I had a difference of about 20 db at 50hz which I was able to bring it at within 8 to 10 db by repositioning the speakers.

Difference persists. Amongst a lot of speakers owned by me over last 2 decades this is first time this had happened. And most importantly Emotiva via its dealer have told that this should not be there. They did not mention that it's within tolerance limits.

It is just a reference. I don't get level match in my room so I just move to either my right or my left. I am surprised you can tell so accurately a difference of less than 1 db.

Maybe the difference measures to 0.6 db max but in program music maybe it alters the tonality a bit of one speaker... Bcoz I was able to find the speaker in 3/3 blind tests.

You are going to have much more variation accross the frequency range. Your issues come from something else. Have you checked if your speakers are in phase? Usually that presents as an unbalanced sound. www.richardfarrar.com/are-your-speakers-wired-correctly/Also if your speakers are in one corner then unbalanced sound is more likely. (Yes I know you swapped positions which should negate this)

Infact they were placed in centre individually with other speaker out of room. Trust me since I was facing issue first time I check it more than a dozen times before bringing it up. I even swapped the output from avr to confirm if the avr has issue.

Its that sound stage is not centred. I can hear it leaning towards one side... The side where I keep that particular speaker.

If your speakers are not centered in the room and in a corner, then the bass reinforcement from the walls can add as much as 10 db to the sound.

Bass is ok. Like kick drums and guitar notes. It's the top and middle like The vocals and higher frequencies which pose issues. And same is seen in the frequency measured response too. The vocals when from music even when mono is selected in the AVR is not centred. Remember I have heard other speakers in the rooms and none posed problems. Infact I used a pair of t2 for many weeks which was given to my brother in law while I bought another pair. Even the previous pair was okay.

Let's see what happens at the dealer tomorrow. I requested a replacement but they won't oblige till they find a flaw at their place. Remember I am in India and not the States.

Just make sure you bring your spl meter with you.
